3) Installation
1. Install the cylinder on the tractor.
2. Connect the power steering hoses to the adapter and tighten to 19.6 – 29.4 N·m {2 – 3 kgf·m}.
3. Start the tractor, operate the steering system, and check for any leaks.
4. PIPING
Replace the oil hoses and pipes if cracks, oil leakage, or other damages are noticed.
Any time a seal is broken, always use sealing tape on the tube fittings to ensure a tight non-leak fit, and torque the fitting to
the specified torque. Don’t taping at the flare nut fitting.
NOTE: When winding seal tape on the thread, be careful not to allow the tape to flow into the hydraulic piping.
Be careful to keep oil hoses and oil pipes off other part. Fix clamps securely.
